present on the device. If no 24 VAC Power
transformer is connected or the fuse (F1) is blown,
the LED will be off.
SCAN LED Indicates the scan rate of the ASM. This red LED will flash on and off at different
speeds indicating the scan rate at which it is
running.
Network
(NET1) RS-485 Communication Status Indicators for NET1 The Green LED will flash to indicate when the device is transmitting data through the associated
port, and the red LED will flash to indicate when
the device is receiving data through the port.

JUMPER CONFIGURATION
AREA
SYSTEM
<Default>
SUBNET
DEVICE TYPE
Various products have the capability of being configured as one of several
possible device types, which represents the network level that it will reside
on in the network architecture (Area, System, Subnet). Other than the one
device acting as a router, all other devices on the same network segment
must be configured the same. Controller may be configured as follows:
Area "Configures the device as an Area level device.
System <Default> "Configures the device as a System level device.
Subnet "Configures the devices as a Subnet level device on a subnet of
similar devices.
For further information, refer to the Delta Controls System Description
Document.
NOTE: This also determines where the DIP or MAC address is mapped
into the devices BACnet address and which other portions of its BACnet
address are inherited when DNA is enabled.
ENABLED
<Default>
DNA DERIVED NETWORK ADDRESSING (DNA)
Derived Network Addressing (DNA), which is dependent on the Device
Type setting and refers to the ability of inheriting portions of its address
from higher-up device’s, is enabled when the jumper is in place across the
jumper pins, and disabled when the jumper is removed.
Enabled <Default> "With the jumper in place, the controller
automatically obtains portions of its overall BACnet device
address (as related to Area and possibly System) from higher-up
devices on the network. This is the preferred method of
addressing the controller in a system of Delta devices.
Disabled "Without the jumper, the controller does not obtain any
portions of its address from higher-up devices. Instead, default
numbers are assumed (for Area, and System or Subnet), which
may be modified via software. This method of addressing is
likely most useful when the controller is installed in an OEM or
other vendor installation and Delta products do not exist higher-
up in the network architecture or where address ranges are pre-
assigned for the installation.
NOTE: Whether or not Derived Network Addressing is enabled, the
Addressing DIP switches are always used to set the device MAC address
and the Subnet device number in the overall BACnet device address.

RUN
<Default>
CLEAR
SRAM MEMORY CLEAR
A jumper is provided so it is possible when necessary to clear out the
SRAM, where the device database resides (including object definitions,
GCL programming, and trend data).
Run <Default> "The battery is connected in circuit and maintains
SRAM memory, even when 24 VAC power is removed from the
product, thereby maintaining both the integrity of the database
and the internal time of the on-board Real Time Clock (for as
long as the battery lasts). This jumper position is required
before applying power for the device to operate properly.
Clear "The battery is removed from circuit and the SRAM memory is
cleared, dumping the database. The internal time of the on-
board Real Time Clock is also reset. This jumper position is
also recommended if the product will be stored for prolonged
periods.
CONTROLLER ADDRESS DIP SWITCHES
Each individual DIP switch represents a pre-defined value (as printed on PCB beside the address block),
which added together forms the device address.
MOUNTING
The Access Control Manager is designed for quick and easy mounting in a number of locations. Normally
this should be within a secured enclosure.
When mounting an ASM, you should always mount an Access Door Module within the same cabinet so a
tamper switch can be wired to the Door Module, giving indication of someone entering the enclosure and
possibly tampering with the Door Module and the ASM. Any standard switch that will mount inside the
enclosure can be used. The tamper switch can be wired so that the circuit is monitored using an EOL circuit
(see ADM-2W704 Installation Guide under Input Wiring for details).
POWER WIRING
The Access System Manager is designed to be powered by either a 24VAC Transformer rated at 40 VA or
the DC Power Out (+12VDC @ 0.25 A) terminal of the ADM-2W704.
WARNING
The Access System Manager needs to be connected properly from the DC Power Out terminal
of the Access Door Module. If you do not connect ground with ground, it may damage the
ASM controller and it will not function properly.

How to make a 10BaseT Ethernet cable
The following two types of 10BaseT Ethernet cables can be made for the ASM:
•the standard patch (straight patch) cable for connection through a hub
•the direct connect (cross patch) cable for direct connection to an ASM
Requirements "The following material is needed for a 10BaseT Ethernet cable:
Item
•two RJ-45 connectors
•RJ-45 crimping tool
•an Ethernet twisted pair cable (TPE CAT5 cable)
To make the Ethernet cables:
1. For either type of cable, sort out the pin numbers of the wires according to the sub-sections Standard
Patch Cable and Direct Connect Cable that follow.
2. Insert the correct wires under the corresponding pins inside a new RJ-45 connector.
3. Ensure the ends of the wires are pushed against the end of the connector and then clamp down the pins
using the correct RJ-45 crimping tool.
Standard Patch Cable
In making standard patch (straight patch) cables, connect the wires to the same pin number on both ends of
the cable, as follows.
